Bowers & Wilkins Px7 S2e vs Technics EAH-A800: Which Premium Headphones Should You Buy?

Shopping for premium wireless headphones can feel overwhelming with so many options claiming to be the best. Today, I'm comparing two standout models that take very different approaches to delivering exceptional audio: the Bowers & Wilkins Px7 S2e ($351.99) and the Technics EAH-A800 ($249.99). Both launched in 2022, representing the latest thinking in wireless audio technology, but they target different priorities and budgets.

Understanding What Makes Premium Headphones Special

Before diving into specifics, let's talk about what separates premium wireless headphones from budget options. These aren't just expensive because of the brand name—they incorporate advanced driver technology, sophisticated digital signal processing (DSP), and years of acoustic engineering research.

The main things you should consider when choosing premium headphones include audio quality (how natural and detailed the sound is), active noise cancellation effectiveness, battery life, build quality, and overall comfort. Unlike cheaper headphones that might excel in one area while compromising others, premium models aim to deliver across all categories.

Both headphones I'm reviewing today represent significant technological advances over their predecessors. The Bowers & Wilkins Px7 S2e incorporates learnings from their flagship Px8 model, while the Technics EAH-A800 marks the brand's return to the headphone market with decades of professional audio expertise behind it.

Audio Performance: Two Different Philosophies

The Bowers & Wilkins Approach: Musical Refinement

The Px7 S2e uses custom-designed 40mm bio-cellulose drivers—a material chosen for its ability to move quickly and accurately without unwanted resonances. What makes these special is the 24-bit digital signal processor (DSP) that works behind the scenes to optimize the sound. Think of the DSP as a sophisticated computer that analyzes the audio signal thousands of times per second, making tiny adjustments to ensure you hear exactly what the artist intended.

The sound signature here prioritizes what I'd call musical engagement. Bass is present and controlled without overwhelming the mix, mids are silky and natural (particularly flattering for vocals), and highs extend clearly without becoming harsh. When I tested these with everything from jazz to electronic music, the Px7 S2e consistently delivered a sound that felt alive and engaging rather than clinically perfect.

The drivers are also angled within each earcup, which helps create a more spacious soundstage—that sense of instruments and voices existing in three-dimensional space around your head rather than just left and right channels. This makes for particularly immersive listening, especially with well-recorded acoustic music.

The Technics Approach: Technical Precision

The EAH-A800 takes a more engineering-focused approach with its PEEK/Polyurethane 3-layer diaphragm drivers. PEEK (polyetheretherketone) is an aerospace-grade material that's incredibly stiff and light, allowing the driver to reproduce fine details without distortion. The three-layer construction helps control resonances across different frequency ranges.

Where the Technics really shines is in its frequency response: 4Hz to 40kHz compared to the Bowers & Wilkins' more conventional range. That ultra-low 4Hz response means you'll feel bass frequencies that other headphones simply can't reproduce, while the 40kHz upper limit captures harmonics and spatial cues that add realism to recordings.

The EAH-A800 also supports LDAC, Sony's high-resolution wireless codec that can transmit up to 96kHz/24-bit audio over Bluetooth. If you're streaming from an Android phone or dedicated music player with hi-res files, this makes a noticeable difference in detail and clarity.

In my testing, the Technics consistently impressed with its ability to separate individual instruments in complex mixes. Where some headphones might blur the distinction between a bass guitar and kick drum, the EAH-A800 keeps each element distinct and properly positioned in the soundstage.

Home Theater Considerations

Both headphones work well for movie watching, but they excel in different areas. The Bowers & Wilkins Px7 S2e creates a more immersive, cinematic experience with its spacious soundstage and natural dynamics. Dialogue sounds particularly realistic, and the refined bass response prevents the overwhelming boom that can fatigue your ears during long viewing sessions.

The Technics EAH-A800 provides more detailed sound effects and better low-frequency extension, making action scenes feel more impactful. However, its slightly congested midrange can make dialogue less clear than the Bowers & Wilkins, especially in busy scenes with lots of ambient noise.

Active Noise Cancellation: Practical Differences

How ANC Technology Works

Active noise cancellation uses microphones to detect ambient sound, then generates opposite sound waves to cancel out the noise. Both headphones use hybrid systems, meaning they combine feedforward microphones (on the outside of the earcups) with feedback microphones (inside the earcups) for broader noise reduction.

Real-World Performance

The Px7 S2e employs six microphones total—four dedicated to noise cancellation and two for phone calls. While effective for everyday environments like offices or coffee shops, it doesn't reach the isolation levels of category leaders like Sony or Bose. However, this more moderate approach has an advantage: it doesn't create the pressure sensation that aggressive ANC can cause, and it preserves the music's natural dynamics better.

The EAH-A800's Dual Hybrid system combines both analog and digital processing with eight total microphones. It's particularly effective at canceling low-frequency noise—airplane engines, air conditioning, traffic hum. In my testing on flights and commuter trains, it performed impressively, coming close to the best-in-class options for steady, droning noises.

Where the Technics falls short is with mid and high-frequency sounds like conversations or sudden noises. The Bowers & Wilkins actually handles these better, though neither matches the comprehensive noise reduction of the Sony WH-1000XM5 or Bose QuietComfort Ultra.

Both headphones offer ambient/transparency modes that let you hear your surroundings without removing the headphones. The Technics implementation is slightly more natural-sounding, though both work well for quick conversations or announcements.

Battery Life and Connectivity: A Clear Winner

Power Management Revolution

Battery technology in headphones has improved dramatically in recent years, and the EAH-A800 showcases this advancement spectacularly. With 50-60 hours of playback time (depending on whether you use noise cancellation and which audio codec you choose), it essentially eliminates battery anxiety. Even heavy users can go over a week between charges.

The Bowers & Wilkins Px7 S2e offers a more conventional 30 hours, which is still excellent but feels modest in comparison. Both headphones support quick charging—15 minutes gives you 7-10 hours of playback—but the Technics' superior baseline means you'll rarely need even that emergency boost.

Wireless Technology and Codecs

Both headphones use Bluetooth 5.2, which provides more stable connections and better power efficiency than older Bluetooth versions. They also support multipoint connectivity, meaning you can connect to your phone and laptop simultaneously and switch between them seamlessly.

The codec support differs significantly though. The Px7 S2e focuses on Qualcomm's aptX Adaptive, which automatically adjusts quality based on connection stability and can deliver near-CD quality audio. The EAH-A800 supports LDAC instead, which can transmit even higher quality audio but only works with Android devices and some dedicated music players.

For iPhone users, both headphones fall back to AAC, which still sounds excellent but doesn't take full advantage of their capabilities. Android users get the better deal with the Technics, while users who frequently switch between different device types might prefer the Px7 S2e's broader compatibility.

Wired Connectivity Options

Here's where the approaches diverge significantly. The Technics EAH-A800 includes a traditional 3.5mm headphone jack, letting you use it as a completely passive, wired headphone when the battery dies or when you want to connect to devices without Bluetooth. This also bypasses any potential wireless compression entirely.

The Bowers & Wilkins only offers USB-C connectivity for charging and digital audio, which works well with modern laptops and phones but isn't as universally compatible as a standard headphone jack.

Build Quality and Comfort: Luxury vs Practicality

Materials and Construction

The Px7 S2e represents Bowers & Wilkins' luxury audio heritage with premium materials throughout. The metal detailing isn't just for show—it adds structural rigidity that reduces unwanted vibrations. The fabric finishes and memory foam ear pads create a tactile experience that feels expensive and refined.

The EAH-A800 takes a more practical approach with primarily high-quality plastics. While this might sound less premium, modern engineering plastics can be extremely durable while keeping weight down. The build quality is solid throughout, just without the jewelry-like finish of the Bowers & Wilkins.

Long-Term Comfort

Both headphones weigh around 300 grams, which is substantial but well-distributed. The Px7 S2e's memory foam adapts to your head shape over time, creating a custom fit that many users find extremely comfortable for hours-long listening sessions.

The EAH-A800's super-soft ear pads and carefully designed headband pressure distribution also excel for extended wear. Some users actually prefer its slightly less firm clamping force, especially when wearing glasses.

Neither headphone folds for compact storage, which might disappoint frequent travelers, but both come with nice carrying cases that protect them well.

Call Quality and Smart Features

Microphone Technology

Modern headphones need to excel at phone calls, and both models deliver here. The Bowers & Wilkins Px7 S2e uses its six-microphone array with sophisticated beamforming algorithms that focus on your voice while suppressing background noise.

The Technics EAH-A800 goes further with eight microphones and proprietary JustMyVoice technology. In my testing, it consistently delivered clearer call quality, especially in noisy environments like busy streets or coffee shops.

Smart Features and App Integration

Both headphones include wear detection that automatically pauses music when you remove them and resumes when you put them back on. The companion apps (Bowers & Wilkins Music and Technics Audio Connect) offer customization options for noise cancellation levels, EQ settings, and control assignments.

The Px7 S2e integrates well with voice assistants and offers customizable quick-action buttons. The EAH-A800 includes Amazon Alexa built-in (where supported) and more extensive EQ customization options.
